What is Sci-fi Horror?

Horror that is peppered with Science Fiction elements. This subgenre blends the two larger genres. Elements such as aliens, robots, and space travel are prominent in Sci-fi horror. This subgenre makes even technology creepy by vilifying it. What if more than the NSA was tapping cell phones? What if savvy tech terrorists hacked your phone to screw with your brain waves? Robots in every form are quickly becoming a commercial reality. When robots with artificial intelligence equal to human consciousness are programmed, when will they turn against us? Hell what if Space Pirates were a thing? What if you are in space or an extra-solar planet and need to survive against something not human?

One sub-genre of Science Fiction that intersects directly with horror is the Space-Horror which taps into the horror of forced confinement, psychological terror of long space travel, and survival against non-human entities. This is particularly popular premise for media such as video games (Dead Space) and films (Aliens)

Sci-fi horror plays on realistic fears as well as far out and mystical ideas.
